The WE-MAIA by Würth Elektronik

Efficient Power Inductor

The WE-MAIA is one of the world’s smallest metal alloy power inductors. It’s efficiency is outstanding and now available in new sizes and extended temperature versions with AEC-Q200 Grade 0 qualification for -55 °C to +150 °C operation temperature in the 4020HT series.

The power inductor was developed for the latest and upcoming switching regulator generations. It impresses with its innovative metal-alloy core material. The frameless design with direct wire connection significantly increases the effective magnetic volume and thus also the power density.
